To all who mitt may 'a mem; I I

Be it known that I, CHARLEY BURNETT, a

Washington Court House, in the' county of Fayette and State ofI'Ohio,'-J have"invented certain new and useful Improvements, in

I his invention relates to building. construction and is designedparticularly as an improved roof construction, [although the inventionis not necessarily limited thereto,

inasmuch as the principles and'structures involved may be applied withequalfacility to sidewall and similarconstructions. I

The main object of my invention resides in a construction designed to be'i veatherproof and water-proof, construc-' tion, all joints areeffectively closed to the admission of moisture and likewise all jointsare so arranged that warping or shrinking in any manner.

will not distort or destroy the construction I This arrangement is alsodesigned with a view of cheapness, the same being far cheaper to installwhen itseifectiveness is considered than structures heresectional viewtaken on the plane indicated by the line 2-2 of Figure 1, and

Figure '3 is an. enlarged detail view disclosing particularly theconstruction and operative position ofthe burred washer element. I 1 IIn these figures, I have illustrated'my 1nvention in connection with aroof, although it is to be understood that the invention is not limitedthereto, as it may be applied with equal facility to side wallor otherconstruction.

In these views, the rafters are designated by the reference numeral landa the ridge pieceby the reference numerallk.

Between the rafters 1, I place a plurality of cross pieces 2 offsetslightly from each other, as shown, so that the nails 3 may be driventhrough the rafters and into the ends of each of the cross pieces'2.

- 'After this, the grooves are covered-by means of metallic V-shapedstrips 8 which are.

shaped to snugly fit the inclined bottoms 7. These metallic strips arein turn secured in position bymeans of nails 9 preferably having leadwashers 1O interposed between their heads and the metallic strips. Themetallic strips are preferably punched for the 'reception of these nailsprior to their application to the roof, and these punchings are formedit from the inside ofthe stripsloutwardly, so as to leave upwardlyprojectin burred portions 11 in connection with w ich the lead washersmust engage themselves when the attaching nails are driven home. Theseburred portions embed-themselves in the lead washers to make the jointsweather tight and water tight and in additiomthese lead washers preventdirect contact of steel on steel and thus rusting is eliminated. Thevnails 9, as shown, are driven into the rafters or cross pieces throughthe meetingedges of I the boards and because of the V-shaped nature ofthe metallic strips, any shrinkage laterally of these boards will onlytend to tighten the joint between the metallic strips and the inclinedbottoms-of the grooves. In this manner, it must be apparent that a veryeffective joint isproduced. Injoining two sections longitudinally, as isshown at 12,

I arrange the'joints together directly over on'eof the cross'pieces2'and space the boards slightly from each other. Into the space thusformed, I place asuitable waterproofing' compound such as a combinationasphaltum 1 '110 I and asbestos compound. 'These mixtures may bepurchased in the open. market and are usually ofa semi-plastic form andwhen;

a. groove is thus filled with it, a very effective water tight andweather tight joint 13 produced. If desired, the entire roof may bepainted with similar weather proofing compound. i. a

From the foregoing description, it will be apparent that I have provideda building construction in which all joints are efectively closed andwhich-at the same time is comparatively cheap to produce. The

jointsare so fo rmed; that longitudinal shrinka'ge'or distortion of theboards is perf'mitted, becausepreferably there is no perman'entconnection between the metal strips 8 and th'e 'groovededges of theboards to prevent such small relative movement as may occur :during theseasoning of the "boards. Any slight lateral movement or dis I tortionwhich may also occur during the seasoning action is permitted for thesame reason, but this only increases the tightness metal strips 8 andtheoffit between the boards themselves.

What I claim, is: In abuildingstructure, in combination, a backing, apair of longitudinally extending rough forming members arranged side byside upon said backing so that theirmeeting v Witnesses lationship withsaid faces, consisting of a plurality of headed securing elementsadapted to be embedded in said backing and formed to pass throughopenings provided in the ridge portion of said strip, said openingsbeing punched out to define projecting bu'rred elements, and a pluralityof i relatively soft metal washers locatedbetween the heads'of saidsecuring elements and strip, said washers being formed to reopeningswhen the securing elements occupy their holding positions. V i Intestimony whereof I afiixmy signature in presence of two witnesses;
